Description Bojan Smojver 2015-11-17 20:24:14 UTC 
Description of problem:
Pure guess in terms of component here, but under wayland, when new windows are opened, they are not positioned in the same way on the desktop as they would be under x11.

Under x11, the window manager appears to be calculating how many windows would fit and then puts the first such windows into the "optimal" position on the top left. For instance, an empty workspace where Gnome terminal is started will get that window in upper left position in a way that would fit maximum number of terminals, but with top and left margin adjusted appropriately. Under wayland, the window is simply positioned in the upper left corner with no margins.

Version-Release number of selected component (if applicable):
mutter-3.18.1-4.fc23.x86_64

How reproducible:
Always.

Steps to Reproduce:
1. Run Gnome under wayland instead of x11.


Actual results:
Different window positioning.

Expected results:
Should be the same?

Additional info:
Eventually, the mouse cursor started playing up under wayland and gnome-shell crashed once, so I would not be able to use it for my session, but this problem is also worth reporting.

I would be great if it could be backported to F-23. Seems like a one-liner.
